I am of two mind regarding several of Nealy's designs. On the one hand, I think the combination of different bevel grinds on the same blade is smart in some ways and sub-optimal in others. On a couple of his designs he has a fairly thin edged hollow grind over most of the blade which transitions to a thick-edged flat grind near the tip. I like that for a tactical blade as you have a good cutting edge for the most part, and a strong tip. The transition between the grinds does interfere with smooth continuous cutting. That is not a big issue for a blade that was designed for defensive use first. All my blades though have to be good utility knives first, and I will make them work for defense.
The other odd thing about Nealy's designs is that they seem rather optimized for thrusting, vis-a-vis the strong tips I've already mentioned, but are very low on handle curves, finger cutouts, or guards that would stop the hand from sliding up on the blade.
I like his designs, particularly the Kinzhal and the Belledau, but find them a little confusing.
